Esterman said that the surgery ''went smoothly,'' adding that Jeremy ''is now resting with complete privacy and no visitors.''

Jeremy, nicknamed the ''Hedgehog'' for his short and hirsute body and known for his large mustache, parlayed his porn star fame into mainstream celebrity status by appearing on the American reality television series The Surreal Life in 2004, and by being featured in an advertisement by animal-rights advocates Peta.

In a Twitter posting on his official account, Jeremy's management said, ''Please keep Ron in your thoughts and prayers for a speedy recovery.''

His memoir, ''The Hardest (Working) Man in Showbiz,'' was published in 2007 by HarperCollins, a division of News Corp .
